GoAccess is an open source real-time web log analyzer and interactive viewer that runs in a terminal on *nix systems or through your browser. It provides fast and valuable HTTP statistics for system administrators that require a visual server report on the fly.
GoAccess parses the specified web log file and outputs the data to the X terminal. Features include:
- Completely Real Time
All panels and metrics are timed to be updated every 200 ms on the terminal output and every second on the HTML output.
- Minimal Configuration needed
You can just run it against your access log file, pick the log format and let GoAccess parse the access log and show you the stats.
- Track Application Response Time
Track the time taken to serve the request. Extremely useful if you want to track pages that are slowing down your site.
- Nearly All Web Log Formats
GoAccess allows any custom log format string. Predefined options include, Apache, Nginx, Amazon S3, Elastic Load Balancing, CloudFront, etc.
- Incremental Log Processing
Need data persistence? GoAccess has the ability to process logs incrementally through the on-disk persistence options.
- Only one dependency
GoAccess is written in C. To run it, you only need ncurses as a dependency. That’s it. It even features its own Web Socket server — https://gwsocket.io/.
Determine the amount of hits, visitors, bandwidth, and metrics for slowest running requests by the hour, or date.
- Metrics per Virtual Host
Have multiple Virtual Hosts (Server Blocks)? It features a panel that displays which virtual host is consuming most of the web server resources.
- Color Scheme Customizable
Tailor GoAccess to suit your own color taste/schemes. Either through the terminal, or by simply applying the stylesheet on the HTML output.
- Support for Large Datasets
GoAccess features the ability to parse large logs due to its optimized in-memory hash tables. It has very good memory usage and pretty good performance. This storage has support for on-disk persistence as well.
- Docker Support
Ability to build GoAccess’ Docker image from upstream. You can still fully configure it, by using Volume mapping and editing
Nearly all web log formats…
GoAccess allows any custom log format string. Predefined options include, but not limited to:
- Amazon CloudFront (Download Distribution).
- Amazon Simple Storage Service (S3)
- AWS Elastic Load Balancing
- Combined Log Format (XLF/ELF) Apache | Nginx
- Common Log Format (CLF) Apache
- Google Cloud Storage.
- Apache virtual hosts
- Squid Native Format.
- W3C format (IIS).
- Caddy’s JSON Structured format.
GoAccess was designed to be a fast, terminal-based log analyzer. Its core idea is to quickly analyze and view web server statistics in real time without needing to use your browser (great if you want to do a quick analysis of your access log via SSH, or if you simply love working in the terminal).
While the terminal output is the default output, it has the capability to generate a complete, self-contained, real-time
HTML report, as well as a
You can see it more of a monitor command tool than anything else.
Build from release
GoAccess can be compiled and used on *nix systems.
Download, extract and compile GoAccess with:
wget https://tar.goaccess.io/goaccess-1.4.6.tar.gz tar -xzvf goaccess-1.4.6.tar.gz cd goaccess-1.4.6/ ./configure --enable-utf8 --enable-geoip=mmdb make make install
Build from GitHub (Development)
git clone https://github.com/allinurl/goaccess.git cd goaccess autoreconf -fiv ./configure --enable-utf8 --enable-geoip=mmdb make make install
It is easiest to install GoAccess on GNU+Linux using the preferred package manager of your GNU+Linux distribution. Please note that not all distributions will have the latest version of GoAccess available.

CowAxess is a GoAccess implementation for Windows systems. It is a packaging of GoAccess, Cygwin and many other related tools to make it a complete and ready-to-use solution for real-time web log analysis, all in a 4 MB package.
If you prefer to go the more tedious route, GoAccess can be used in Windows through Cygwin. See Cygwin’s packages. Or through the GNU+Linux Subsystem on Windows 10.
Usage / Examples
- To output to a terminal and generate an interactive report:
- To generate an HTML report:
goaccess access.log -a > report.html
- To generate a JSON report:
goaccess access.log -a -d -o json > report.json
- To generate a CSV file:
goaccess access.log --no-csv-summary -o csv > report.csv
- GoAccess also allows great flexibility for real-time filtering and parsing. For instance, to quickly diagnose issues by monitoring logs since goaccess was started:
tail -f access.log | goaccess -
- And even better, to filter while maintaining opened a pipe to preserve real-time analysis, we can make use of
tail -fand a matching pattern tool such as
tail -f access.log | grep -i --line-buffered 'firefox' | goaccess --log-format=COMBINED -
- or to parse from the beginning of the file while maintaining the pipe opened and applying a filter
tail -f -n +0 access.log | grep -i --line-buffered 'firefox' | goaccess -o report.html --real-time-html -
Multiple Log files
- There are several ways to parse multiple logs with GoAccess. The simplest is to pass multiple log files to the command line:
goaccess access.log access.log.1
- It’s even possible to parse files from a pipe while reading regular files:
cat access.log.2 | goaccess access.log access.log.1 -
- Now if we want to add more flexibility to GoAccess, we can use
zcat --forceto read compressed and uncompressed files. For instance, if we would like to process all log files
access.log*, we can do:
# zcat --force access.log* | goaccess -
Note: On Mac OS X, use
gunzip -c instead of
- Also, it is worth pointing out that if we want to run GoAccess at lower priority, we can run it as:
nice -n 19 goaccess -f access.log -a
and if you don’t want to install it on your server, you can still run it from your local machine!
ssh -n root@server 'tail -f /var/log/apache2/access.log' | goaccess -
